18-gauge rose gold Artistic Wire, 20ft (6.6 yard) spools. Permanently colored copper wire is used in a variety of jewelry and craft projects. Silver plated Artistic Wire has a layer of pure silver underneath the enamel color. The wire has an incredible high-shine and brilliance that needs to be seen in person to be truly appreciated. Colors may vary. Use 18-gauge wire for chunkier jewelry and craft projects that still require a soft, malleable material that's easy to bend.
